Vehicle: 2002 Ford F150 FX4
Engine: 5.4l 2v Triton V8
Mileage: 52,050 miles
Symptoms: Engine cranks and cranks but doesn't start. Pretty obvious that the issue is in the fuel system. Problem is intermittent, usually starts fine but 1 out of every 5 or 6 attempts will fail. Has occurred usually with less than 1/2 tank, but it did this once with a full tank. The usual "fix" to get started is to cycle the key, then she starts right up and runs like a champ!
Research: Google searches have indicated that I should turn the key without starting and listen for fuel pump running in the tank as that should eliminate many possibilities. Pumps priced around $350 + on Advance Auto Parts website.![Eek](https://www.f150forum.com/images/smilies/eek.gif)
Also found that a $99 Electronic Fuel Controller typically corrodes and goes bad, but later discovered 97-03 F150's doesn't have those... darn, there goes the cheap fix.![001 Unsure](https://www.f150forum.com/images/smilies/001_unsure.gif)
Results: Weather was too bad over weekend to get on ground and check underneath truck for pump sounds and anything else with fuel system. Hoping to check this coming weekend but looks like weather will turn bad again before I get back in town.
Does anyone have any suggestions as to what else I should look for/listen for to help diagnose this issue? Thanks!

Its fuel pump most likely. Check and see if you have pressure from your fuel under the hood. And you can buy just the pump instead of the whole assembly for around $100

Thinking about changing it myself. Found some instructions elsewhere, hope I don't get in over my head. Seems like the hard part is the time spent getting access to the pump than the pump installation itself.
Going to borrow my cousin's fuel pressure tester tomorrow if I don't end up going out of town.
